What should you know about genetic test food intolerance?

Food intolerance usually describes difficulty digesting or processing a food component rather than an immune reaction. Symptoms may include bloating, cramps, loose stools or diarrhoea, and they can have several causes. A genetic result can be relevant for selected inherited traits, but a result does not prove that a food is responsible for symptoms today. A negative result also does not rule out every non-genetic intolerance. Food Allergy is a separate immune condition and needs a different assessment.

Bring the report, your medicines and a record of meals and symptoms to a clinician. Food Intolerance Testing may be considered alongside history and, when appropriate, a planned elimination and reintroduction process. Do not cut out multiple food groups based only on a mail-order panel. Nutrition Counselling can help protect energy, fibre and micronutrient intake while a suspected trigger is assessed. A clear pattern—what was eaten, how much, and how quickly symptoms appeared—is often more useful than a long list of unconfirmed exclusions.

Book an appointment if symptoms keep returning, disturb sleep, limit eating or cause weight loss. Get urgent help for severe pain, dehydration, repeated vomiting, blood in stool, swelling of the lips or tongue, wheezing or breathing difficulty. These urgent allergy features should not be managed by changing your diet alone.

What does this particular genetic finding actually predict? Which diagnoses should be considered? Should I trial removing one food at a time? How can I reintroduce foods and avoid nutritional gaps?
